Fix regression introduced in d468fcbb / OTP-14816
The ~p format specifier made file:consult/1 hysterically slow on one of our test machines that had a unicode character in the root of the code path; all paths were printed as lists and indented with way too much whitespace. Using ~w avoids this issue by never indenting.
